Power Integrations launches SCR dimming LYTSwitch-7 LED driver IC

by:MOSO     2019-12-24

LYTSwitch- The 7 IC can provide phase cuts with wide dimming range and unidirectional dimming response characteristics (SCR)Dimming scheme. The LED driver can achieve an efficiency of more than 86%, which is about 2% higher than that of traditional dimming products, and also has high power factor, accurate adjustment rate and comprehensive protection function. They are suitable for both low input voltage or high input voltage designs and a wide range of input designs in US commercial lighting applications. The operating voltage range of these designs is between 90 VAC and 305 VAC, and SCR dimming is required in low voltage application environments.

Hubertus Notohamiprodjo, director of product marketing for Power Integrations, said: Our latest LYTSwitch- The 7 LED driver IC can provide a robust and highly reliable design while minimizing the number of BOM components, which is about 40% less than that of traditional circuits. The built-in 725 v mosfet provides better withstand voltage performance during input surges. At the same time, the design of the no-discharge circuit can ensure that under the condition of being compatible with many SCR dimmers, excessive heat will not be generated inside the driver, so the designed driver has higher efficiency and reliability.

like all Power Integrations LED drivers, LYTSwitch- The 7 IC provides a series of protection functions, including a thermal turn-back protection function that can immediately shut down the driver. Under abnormal high temperature environment, this function can automatically reduce the output current and dim the LED light, thus protecting IC, driver and the whole lamp. Developers have found that the hot turn-back feature can help reduce the cost of electrical and mechanical costs to meet reliability goals. Because IC can automatically control the abnormal increase of temperature without extinguishing the bulb. The device also provides open circuit, short circuit, input and output overvoltage, overcurrent, and safe working area (SOA)Protection. LYTSwitch- 7 IC meets many international standards: DOE Level 6 (External Power Supply) , CEC Titles 20 and 24, energy star®2nd. Version 0 bulb energy efficiency specification, nema ssl-7A and EN61000-3-2 (C &D).

The main applications include low-cost A19 bulbs, small-sized bulbs (Such as candle lights and GU10 bulbs), Commercial and industrial applications, ceiling lights and downlights. LYTSwitch-7 IC samples are now available for order. The unit price of the device is 0. 10,000 pieces based on the order quantity of pieces. 33 dollars. There are now two reference designs (DER-539 and DER-540) Available for download from Power Integrations: https://www . Power. Com/lytswitch-7.
